摘    要:目的]研究细果角茴香中总黄酮的最佳提取工艺,并测定其含量.方法]以总黄酮含量为考察指标,以甲醇浓度、料液比和提取时间为考察因素,通过正交试验确定提取总黄酮的最佳条件.结果]吸收曲线测定结果显示,总黄酮在510 nm处有最大吸收.正交试验结果可知,最佳的提取条件为A1B2C2,即甲醇浓度为50%,料液比为1∶15(g/ml),超声提取2次,每次提取时间为20 min;在此条件下,总黄酮的含量最高为48.63 mg/g.结论]该方法操作简捷,结果准确可靠,提取效率高.

关 键 词:细果角茴香(Herb  of  Thinfruit  Hypecoum)  超声波法  总黄酮  提取工艺  含量测定

Abstract:Objective] To study the optimal extraction technique for total flavonoids in Hypecoum leptocarpum and determine its content.Method] With total flavonoids content as investigation indcx,methy alcohol concentration,solid-liquid ratio and extraction time as investigation factors,the optimum conditions for extracting total flavonoids were determined by orthogonal test.Result] The optimum conditions for extracting the total flavonoids by reflux are as following:material-liquid ratio:1∶15,50% methy alcohol,ultrasound extraction 2 times and 20min for each time.Under the above conditions,the highest content of total flavonoids in H.leptocarpum is 48.63 mg/g.Conclusion] The method is easy operation and its result is accurate,extraction efficiency is higher and can be used for study on H.leptocarpum.
Keywords:Hypecoum leptocarpum Hook  f  et Thoms  Ultrasonic extraction  Total flavonoids  Extraction process  Content determination
